low-temperature geochemistry, geobiology, surface processes


Broadly, my research focuses on the biogeochemical cycles of carbon, oxygen and sulfur with the intention of understanding the links between physical transport processes and chemical reactions. For this work, I combine laboratory experiments, field measurements, and numerical models.
